IMPROVEMENT IN HARVESTER-RAKES.

TO ALL 'WI-IOM IT MAY CONCERN:

Be it known that I, EDGAR M. SMITH, of the city, county, and State of New York, have invented certain new and useful Improvements in Combined Rakes and' Beuters for IInrvesting-ilachines; und I do hereby declare the following to be n full, clear, and exact description of the some, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents, in perspective, so much ofa combined reke and 'bea-ter as will illustrate the invention. Figure 2 represents an elevation of the sume, and v Figure 3 represents n portion ofthe appara-tus ns detached, to better' represent it and its connections. Similar letters ot' reference, where they occur in the separate figures, denote like parts of the mechanism in all of the drawings. i

My invention relates to that class of raises and heaters which perform all the duties of a reel and at raking' apparatus, the rakes being rnkes or beaters as the operntor may desire, or the quality of the groin demand, while the beaters enter and bear the standing grain up to and against the action ot the cutters; and my invention consists, first, in the manner of edonguting and then shortening the rnkes, so that they may sweep a platform that is not merely en nro of a. circle, but much longer'or greater in extent than such, and deliver the grain behind the machine;v and my invention further consists in the manner in which I enuse the rakes to roll in their bearings to pass the wheel on that side, and to put themselves in position to act as beaters, or to roll back and become rukes to clear the platform, as the opera-tor, by or through a trip-mechanism that he een move ormot, may desire.

To enable those skilled in the` nrt lo nuke and use my invention, I will proceed to describe the sume with reference to the drawings. l n

A represents a'post, column, or frame, on which the rnkes and beutcrs are supported, and upon which they :ire revolved by any suitable dri.'ingmgehnnism connecting the rake-plate B with the driving-wheels of a haNesting-machine. y I

"io suitnble lugs, a a, upon the rake-pluto B, nre pivoted the rakes e e and the beaters D D, and the rnkcs and boaters being in pairs, and hung at dinmetricnlly opposite points on the revolving plate B, they ere linked together by adjust-able links l) Z, so that the felling of one muy aid in ruisingdts mate or fellow, andV so that thun its mute climbs the cam in rising, thus making un equalizing or compensating movement. l

The beaters I) nre nmde of wood or any other light und strong materiel, and are set and secured in metal hearings, d, upon which there is :1 projection, c, to -trip the rnk'es and allow them to run buck or shorten aft-er they have been elongated to sweep nn irregular-shaped platform. As these beaters have n, continuous rotation, and rise und lnil in every rotation by passing over the cum-shaped ledge E, no further description of thorn need he made.

The rnkcs, however, hav sever-ul motions or functions, which vwill be described.

In the first place, the rake-Etnies c c have u longitudinal sliding motion in their metallic heads F, which motion is controlled by u spring-catch, G, the bolt c ot' which takes into holes or against shoulders on the sliding portions of said rakes, to lock und release thorn, ns the oase maybe. The tail-ends,j`, of' the springcutchcs G, when they come against tlio projections e on the bentcrdtoltler, throw or draw out the bolts c, and :is this Contact takes plnco when the ruko is in quite u vertical position, as shown in iig. 2, the reke-stnle slides beek into its socket or bearing-plates, F, by its own weight or gravity, but is run out positively by a projection, g, on the sliding portion taking against the exterior of n cam-ruil, II, which is secured tothe post A, and extends therefrom around to another support, I, to which it is secured at thnt'end. The rake c has but this longitudinnl sliding und its rising and fnlling motion as it 'rides over the cams E H; but the rake e, in addition to its elongnting und rising trilling motion, an'd its dropping back or shortening, has n rolling motion to and fro iround its stale-bearing, which rolling motion is controlled by the driver at his will, who, by drawing or pulling the cord lr, throwsl up e. trigger or tripper,l 2', as 1shown by red lines in Iig. 2, and when this tripper i is thus thrown up, it catches against the bent endj of a pushing-lever, 7c, that has a slot, l, and pin, m, that allows it an endwise movement, and a pin, n, in the piece F, at the forward end of this pusher, throws up that end ofthe pusher against a bent arm, J, that is on the rake-stale c, and the pusher continuing its motion, its catch o takes the hentarin and rake-stale, and moving it outward until its rearmost finger K has 'passed beyond the plato l", when, there being nothing more to hold the rake, its teeth drop downward by ythe rolling oi` the rake-stale in its bearings; and just when this rolling or turning motion has taken place, then the tail-end,f, et' the springbolt Gr, strikes against the projection a, and the rake runs back in its plates or bearings F, and it isin position fer raking oil` the platform on its round, and when'it arrives at the peint where the grain is deliveredupon the ground, and after the delivery, the rake is moved slightlyoutward, so thatl 'it can roll in its bearings, (this being prevented during the sweeping oil` of the platform,`) and the bent arm J, striking against the stationary camplane L, turns the ralie a-quarter round, so that its teeth will be, horizontal, and th'e back of the rake towards the standing grain. It', now, the tripper is allowed to fall, so as not to touch the bent end j ofthe pusher In, then this rake will go around in this position, and aet as a beater, and continue so to act until thc driver or operator throws up the trigger, and when that is done, and so long as it is up, (and it may be fastened up'bj :the set-screw 1),) so long this parteL the machine will be a rake, so that it is a rake for clearing theplatform l-ora'beater for bringing in the gra in to the cntters,which`ever the operator desires; and, though I have only described oneof these instruments, viz, thatone, c, as being thus a rake or abeater, it is obvious that the other one, c', could be similarly arranged and operated, if so desired. u y i Just before the rear portions of the ralres strike the stationary cam E to4 ride upon it, they come against a friction-roller, M, adjustably set upon or against the cam-rail H, and this roller starts the rakes upward gently, and avoids the jar that would b e lincident to their coming rst against the stationary cam-plane E.

There are some other slight details ofthe mechanism, but as they are clearly shofw'n in the drawings, further description is not regarded as essential. v

Having thus fully described my invention, what I claim therein as new, and desire te secure by Letters Patent, is-

1. In-revolving rising, falling, and rolling rakes, the elongating and shortening of saidi ralies, by sliding them in their bearings, so that they will sweep an irregular-shaped platform, substantially described.

2. I also claim locking and unlocking and moving of tbejakes out andin by devices, substantially as herein described, that are self-acting, and require no attention on the part of the operator, substantially as described.

3. also claim the combination of the trigger z' and sliding lever Ic, for moving the rake out, so that it can roll in its bearings, and thus become a ral-:e instead of a beater at the will of the operator, substantially aS described.
